This invention relates generally to a hydroponic produce production anddisplay apparatus and, more particularly, the invention relates to ahydroponic produce display apparatus allowing home, kitchen, in-storeand market display and storage of unpicked, growing vegetables and herbsto consumers.

2. Description of the Prior Art

Traditionally, agricultural produce displayed in supermarkets, farmer'smarkets, or other venues has previously been harvested and transported,and as such often suffers wilting and cosmetic blemishes, damage to bodyand structure, loss of nutrition, and the resulting negative effects onconsumption. By presenting living, growing crop plants in themarketplace showing none of the negative characteristics of harvest andtransport, many of these hurdles to consumption can be overcome, andstorage life of the harvested product increased dramatically.Additionally, presenting crops in a way that allows consumers to chooseand harvest plants themselves introduces a positive tactile experienceto consumers that contributes to a pleasing customer experience.Additionally, crop plants that are not picked in the marketplace arekept alive and healthy and can be returned with the productioncontainers to the producer to be harvested and introduced to the marketin a more traditional manner. The shelf life of live plants in such asystem dramatically exceeds the shelf life of harvested vegetables andherbs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated in FIGS. 1-14, the present invention is a hydroponicproduce display apparatus, indicated generally at 10, allowing in-storeand market display of unpicked, growing vegetables and herbs toconsumers. The hydroponic produce display apparatus 10 described hereinsustains plant life and vitality by supporting the irrigation anddisplay of discreet, modular hydroponic production containers 12 invarious forms, including nutrient film technique troughs, drip techniquetroughs, aeroponic tubes, and vertical hydroponic towers.

Being lightweight and portable in design, the hydroponic produce displayapparatus 10 of the present invention is easily transported from marketto market as well as being permanently or semi-permanently plumbed andplugged into electrical outlets for long-term displays or in-home use.Since hydroponic containers 12 on display are exchanged on a regularbasis to ensure proper plant growth- and as such, the hydroponic producedisplay apparatus 10 described herein is designed primarily to sustainplant appearance and vitality until on-site harvest at the market orstore, not to provide plant nourishment or promote plant growth.However, by utilizing a nutrient solution the system, some embodimentsof the present invention may be used for home and commercial hydroponicproduction.

In one embodiment of the hydroponic produce display apparatus 10 of thepresent invention, the hydroponic produce display apparatus 10 utilizesa rectangular basin 14, rounded on the two narrow ends and varying ininternal volume from fifteen (15 gal.) gallons to three (3 gal.)gallons. In addition, the basin 14 has a drain valve 16 with a hosefitting attached to its wall or base. The basin 14 is secured upon asteel framework 18 and enclosed in a decorative skirt 20 of wood, metal,or plastic varying in height from approximately six (6″) inches toapproximately two (2′) feet, encircling the circumference of the basin14.

Flush with the top of the decorative skirt 20 runs a drainage trough 21circling the inner circumference of the decorative skirt 20. The troughcan be replaced with individual grates 22 in some embodiments. Thetrough or grate 22 has an internal return pipe at one end that transferswater from the trough down to the basin 14 resting in the middle of thedisplay. The top of the trough is covered by the decorative grate 22 setin a plastic or metal drain that forms an inset approximately three (3″)inches to twelve (12″) inches in width. From the inner edge of the insetrises a display face constructed of wood, metal, or plastic flashingrising to the display top, either straight or tapering inward slightlyas it rises, and rising to a height of approximately two (2′) feet toapproximately eight (8′) feet. In some embodiments, the display facerises from the front of the grate 22 with inset channels 24 that holdvertical hydroponic towers 12. In this embodiment, the grate 22 ismostly covered by the face of the display and the vertical towers 12inset into the display rest on the grate 22 with their faces flush tothe face of the display. The display face is fixed to a steel, wooden,or plastic framework. The top of the display can be open or covered by aplastic, wood, or metal decorative top.

The display face of the display can be configured in a number of waysmeant to attach hydroponic towers or troughs 12 to the display. In oneembodiment, the display face has the inset channels 24 that allow thevertical towers 12 to stand flush with the face of the display. Inothers, a series of brackets 26 of variable spacing, having flat, upwardprojecting hooks of metal for attaching vertical hydroponic towers 12directly to the display. This hook corresponds with the complementarybracket on the backs of the vertical hydroponic towers. When attached,the vertical towers 12 stand upright, with the bottoms of the towers 12resting on the grate 22 of the inset 24, with one or more brackets 26securing the tower 12 to the display. In this configuration, the plantsgrowing in the towers face outward, away from the display. Towers 12 canbe displayed on one side or both of the display or two displays can beplace back to back to display completely encircling the display.Advertisement and information boards can also be attached to thesebrackets 26 offering information on the produce being marketed. Whenhorizontal troughs are being secured to the display, a framework 30 issecured to the upper display brackets that support the horizontaltroughs as a series of tapered shelves, with one end of all the troughsslightly elevated above the other to facilitate drainage. At thedepressed end, a square or circular pipe stands vertically, withcorresponding ports to receive the draining end of the troughs. Thebottom of this drainpipe rests on the inset grate 22 and drains into theinternal drainage trough 21. Depending on the type of display 10,troughs will be displayed as above on both flat sides of the display 10,with informational and advertisement boards displayed on the roundedends of the display 10. Irrigation of the displayed plants within thehydroponic produce display apparatus 10 of the present invention isaccomplished using a tubing system 32 that rises either from the basin14 in the display base, or from a three-way “Y” fitting having a valvedhose fitting attached on one side, while on the other side interruptingthe tubing system 32 above the basin. A pump 17 rests in the basin 14and pumps water from the basin 14 through a valve and through the “Y”fitting to an ultra violet sterilizer. Water flows through thesterilizer to the top of the display where a “tee” interrupts theirrigation tubing 35 having a valve on both of the downstream endsallowing water to be diverted via valves to two different irrigationstructures. The first irrigation structure is employed when verticalhydroponic towers are being displayed. It consists of a ring ofirrigation tubing 35 radiating from the center of the display to form aring around the upper edge of the display backing. Misting, spraying ordripping nozzles 33 are inserted into the irrigation tubing atappropriate intervals so that water is introduced to the tops of thehydroponic towers. The second irrigation option is employed whendisplaying horizontal hydroponic troughs and consists of a verticaldrop-pipe that hangs over the exterior of the display back, on the endof the display that supports the raised ends of the hydroponic oraeroponic troughs. From this pipe feeder tubes emerge horizontally andare inserted into the raised ends of the hydroponic troughs. To the endsof these feeder tubes a variety of spraying, misting, and drippingnozzles can be attached, depending on display crop requirements.

In another embodiment of the hydroponic produce display apparatus of thepresent invention, as best illustrated in FIGS. 11 and 12, hydroponictowers only are displayed, being held erect by a support arm 40 of metalattached to a plastic tank base 14, or by the base itself. Inembodiments where the base is the primary support for the hydroponictower, as illustrated in FIGS. 13-14, support is achieved by supportingthe tower 12 using the hole in the lid of the base 14, while holding thebase 14 of the hydroponic tower 12 in place with either pegs or a cup onthe end of a support pillar rising from the bottom of the base 14through the interior. Similarly to the above-described invention, thetower 12 is irrigated from the top and drains into the basin/base 14,which collects the irrigation solution to be pumped back to the top ofthe tower by a small submersible pump 17 within the basin/base. Thisbase 14 can rest upon a metal stand, rest directly on the floor, or havewheels to make transport easier. The cord for the pump 17 emerges fromthe rear of the base 14. The base 14 may or may not have a removablecover 23 for aesthetic appeal or to control algal growth within the base14. This particular embodiment is also well-suited to dual use for homehydroponic production as well as plant preservation and display.

The hydroponic produce display apparatus 10 of the present invention hasthe potential to dramatically increase both the shelf life and qualityof produce at market as well as change consumer experiences at market.The apparatus 10 takes advantage of modularity in hydroponic productionsystems to introduce a new means of marketing produce to consumers, andto offer new methods incentives for wholesale and retail marketers toutilize locally-produced vegetables and herbs. Potential markets for thehydroponic produce display apparatus 10 include farmer's marketretailers, commercial and restaurant kitchens, grocery stores andspecialty crop stores as well as home produce consumers.

The hydroponic produce display apparatus 10 of the present invention isunique in form and function over traditional display technology hasconsisted of bins or containers with doors since the apparatus 10 isconstructed to form a housing that incorporates unharvested plantpropagation containers. It functions as a life-support system forhydroponic produce. The irrigation system 32 is essential to thefunction of the display allowing at-market displays that irrigate theroots of unharvested, living vegetables. The hydroponic produce displayapparatus 10 is unique in application resulting in tangible benefitsthat offer a distinct advantage over the use of traditional bin andrefrigerated displays, including elimination of spoilage (produce has anindeterminate shelf life), elimination of refrigeration costs (energyand equipment), allowing secondary use and distribution of uncut produce(eliminating another source of waste for producers), and elimination ofmost packaging and harvest-related labor costs for producers. Thehydroponic produce display apparatus 10 provides either horizontal orvertical brackets or channels to retain horizontal or vertical plantproduction equipment and is essentially a storage device as much as adisplay device eliminating the need for refrigeration. Towers andtroughs are exchanged by the producer on a regular basis with harvestedcontainers being removed, and unharvested containers being installed inthe hydroponic produce display apparatus 10.
